One of the more versatile of Eichrom's analytical products is TEVA Resin. It has been applied on a routine basis to the analysis of technetium, the measurement of the tetravalent actinides, and the separation of americium from lanthanides. It is used alone or can be readily combined with other…

The same columns used for our standard 2mL pre-packed columns, these polypropylene columns have an inner diameter of 0.8cm and a snap off tip. Use when a slightly different sized column is required for the analysis. The columns are supplied in packages of 100, with 100 caps, bottom frit inserted…

GPC-SEC Calibration Standards (2714X77 to X79) Three different polystyrene standard kits are available for organic GPC column calibration. Each kit contains individual monodisperse polymers that cover low, medium and high molecular weight ranges. Each standard lot is characterized using low-angle…

These columns, nominally 20mL, have an inner diameter of 1.5 cm and a "packable" volume of 17mL. Use them when a large bed volume of one of Eichrom's extraction chromatography or ion exchange resins is required. Columns are supplied with bottom frit pre-inserted, in packages of 20,…

For GC analysis of total petroleum hydrocarbons (TPH) in water Environmentally safer than previous methods Calibration standard available as diesel #2/motor oil and diesel #2/mineral oil 500 μg/mL each in acetone, 1 mL/ampul (1 mL is enough mix to spike one quality control sample) …

In recent years, quality requirements as outlined by ISO 9000, GLP, GMP and NAMAS have assumed increasing importance. As a consequence, the recommendations of pharmacopoeias have become more influential in the pharmaceutical industry. Formal performance verification of UV-Visible spectrophotometers…

Bond Elut C8 is very similar in property to C18, but is not as retentive for non-polar compounds due to its shorter hydrocarbon chain and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly-retained for effective elution. The potential for polar…

Eichrom's TRU Resin is an extraction chromatographic material in which the extractant system is octylphenyl-N,N-di-isobutyl carbamoylphosphine oxide (abbreviated CMPO) dissolved in tri-n-butyl phosphate (TBP). The bed density of TRU Resin is approximately 0.37 g/mL, with a working capacity of 2 mg…

The extractant system in Eichrom's Sr Resin is 1.0M 4,4'(5')-di-t-butylcyclohexano 18-crown-6 (crown ether) in 1-octanol.A 40% (w/w) loading of this organic solution is loaded onto an inert chromatographic support. The bed density of Sr Resin is approximately 0.35 g/mL.

Eichrom’s DGA Resins are extraction chromatographic materials in which the extractant system is either N,N,N’,N’-tetra-n-octyldiglycolamide (DGA Resin, Normal) or N,N,N’,N’-tetrakis-2-éthylhexyldiglycolamide (DGA Resin, Branched). The bed density of both DGA Resins is approximately 0.38 g/mL, with…

Bond Elut ENV, a PS/DVB polymer, is designed for the extraction of polar organic residues. It contains 125 µm spherical particles with a high degree of cross linking, advantageous for high volume, fast flow-through applications.

Compare your column’s performance to the test chromatogram shipped with your J and W column from Agilent. The column test standard contains components that test the column for resolution characteristics, efficiency, and inertness. The test mixes are supplied at a concentration of 250…
